This is a video player that was created for people who are early adopters of the new north American ATSC3.0/HEVC broadcasting standard. Most major US cities have conducted a rollout of this new broadcasting standard that supports 4K HEVC with AC-4 audio, over-the-air (OTA), television broadcast streams.
For owners of SiliconDust HDHomeRun 4K tuners, viewing an ATSC3.0 video stream is as easy as entering the URL for a particular channel as found in your tuner's channel lineup. I.e. http://x.x.x.x:5004/auto/vyyy.y Replace the X's with the IP address of your tuner and replace the Y's with the channel number you want to watch. Allow 10 to 15 seconds of buffering before the video/audio appears.
The player also supports playback of locally stored files.
